Microsoft’s own press conference for Mobile World Congress doesn’t begin until 6:30pm tomorrow (Sydney time), but someone inside Redmond accidentally hit the publish button a little bit too early. They revealed that it will be announcing a the Lumia 640 and the 640 XL at its press conference.

The post – now removed, but still available in Google cache – was first spotted by WinBeta. According to the rumours, the Lumia 640 and 640 XL are the company’s new low-end smartphones. Leaked specifications say that the Lumia 640 will have a 5-inch display and a quad-core Snapdragon processor. The XL version will no doubt feature a bigger screen.

Either way, we’ll keep you informed at what Microsoft announces from 6:30pm tomorrow evening (Sydney time).
